Central Avalanche Hazard Forecasting : Interim Report

Description: This report summarizes the first year of activity under Washington State Department of Highways project Central Avalanche Hazard Forecasting (Agreement Y-1700) to test the feasibility and effectiveness of central avalanche forecasting for the Cascade Mountain Passes and adjacent territory. This project explores the possibilities of improving both mountain weather and related avalanche forecasts for use by the WSDH during winter operations in the mountain passes, and, secondarily, explores the usefulness of an area-wide forecasting service to other, cooperating agencies. The eventual aim of this work is to establish the technical and administrative framework for an operational, on-going mountain weather and avalanche forecasting service for Western Washington under joint support of interested public agencies.
